Hi
I use Ccleaner since many years and I always keep a backup when I clean my registry using Ccleaner. At each scan I need to confirm that I want to backup the registry before fixing it. I think that you should add an option to always backup the registry automatically without asking the user. To do this, you should create a Backup folder in the AppData folder (or somewhere else) and save the "cc_20160520_074823.reg" files there automatically. You should also add an option to show this folder thru Ccleaner to restore a backuped reg file.
I hope to see this feature really soon!!
Thank you!
